WebAn inflection point only requires: 1) that the concavity changes and 2) that the function is defined at the point. You can think of potential inflection points as critical points for the first derivative — i.e. they may occur if f" (x) = 0 OR if f" (x) is undefined. An example of the latter situation is f (x) = x^ (1/3) at x=0. Relevant links: WebFeb 2, 2024 · A point of inflection is defined as the point where a function changes from convex to concave or vice versa. For a function f ( x), this is frequently mathematically defined as the point where f ″ ( x) = 0, since f ″ ( x) describes f ( x) 's curvature [1]. images of resort designer shops images of resin sheds
